Objective Ventriculoperitoneal shunt (VPS)is preferable in treatment for normal pressure hydrocephalus (NPH). In this study, the factors related to the motor recovery after VPS were analysed.Method Twenty-six patients were treated with VPS, and four factors, that are duration of symptoms, open lumbar puncture(LP) pressure, improvement after LP ,and motor recovery of twelve months after operation,were assessed. Results Twelve months after VPS, the better motor recovery after VPS was related to shorter duration of symptoms, higher open LP pressure, and symptom improvement after LP. Conclusion The patients with shorter duration of symptoms, higher open LP pressure, and symptom improvement after LP are often responsive to VPS.

Objective To investigate the epidemiological characteristics and drug sensitivity of non-typhoid salmonella in Zhongshan city.Methods We collected the positive cases of non-typhoid salmonella in children of Zhongshan city from 2013 to 2015.The sex,age,place of residence,onset time and main serum type of these cases were collected.The characteristics of the cases were described by descriptive epidemiologi-cal study.Results From 2013 to 2015,3 040 stool specimens from patients with enteritis were collected and 402 strain of non-typhoid salmonella were separated out. The total detection rate was 13.22%,the annual detection rate were 10.26%,12.21% and 16.76%,respectively.The peak period was from July to August every year.Of the 402 children,240 were male,162 were female,and the ratio was 1.48:1.The minimum age was 1 month,the maximum was 5 years and 8 months,the mean age was 13.62 months.All patients were characterized by diarrhea and fever,including 64 cases of bloody stool and 1 case of sepsis.The most com-mon serotypes were 4,5,12:i:-and 4,12:i:-.The resistant strains were salmonella typhimurium and variety salmonella typhimurium strains.From 2013 to 2015,the resistance rate of ceftriaxone and ceftazidime in non-typhoid salmonella isolates increased linearly (ceftriaxone: 17.35%, 26.23%, 39.01%; ceftazidime:12.24%,17.21%,30.77%).The differences were statistically significant(χ2=30.3,P<0.01;χ2=26.3, P<0.01).Conclusion The positive rate of nontyphoid salmonella increased year by year from 2013 to 2015.The most common serotype was salmonella typhimurium, and the resistant strains were salmonella typhimurium and salmonella typhimurium variety.The resistance rate of non-typhoid salmonella to ceftriaxone and ceftazidime increased year by year,and the highest rate of ceftazidime resistance was in July 2015.Non-typhoid salmonella was more resistant to ceftriaxone than ceftazidime.

Objective: To analyze the relationship between family behaviors and overweight/obesity in primary and junior school students aged 6-14 years in Xuzhou, and to provide a reference for a targeted measure to prevent and control overweight and obesity. Methods: Using multistage stratified cluster random sampling, a total of 6 220 students aged 6-14 years old from 10 primary schools and 10 junior schools were investigated by a self-designed questionnaire. Chi-square and multivariate Logistic regression models were used to explore the relationship between family behaviors and overweight/obesity in primary and junior school students. Results: The rate of overweight/obesity in primary and junior boys was higher than that in primary and junior girls. The rate of overweight/obesity in urban students was higher than that of rural students(P<0.05). The Chi-square analysis showed that overweight of parents, irregular breakfast, eating fast food, eating sweets, drinking sweetened beverage, long screen time and short sleep duration were risk family behavior factors of overweight/obesity in primary and junior boy students(P<0.05). The risk family behavior factors of overweight/obesity in primary and junior girl students were overweight of parents, irregular breakfast, eating fast food and eating sweets(P<0.05). The risk family behavior factors of overweight/obesity, such as drinking sweetened beverage and short sleep duration, were also related to primary girls(P<0.05), and long screen time was related to junior girls(P<0.05). The multivariate Logistic regression showed that such family behavior factors as irregular breakfast(OR-boy=1.58, OR-girl=1.74), eating fast food(OR-boy=1.37, OR-girl=1.11), eating sweets(OR-boy=1.85, OR-girl=1.52), drinking sweetened beverage(OR-boy=1.64, OR-girl=1.33) and short sleep duration(OR-boy=1.56, OR-girl=1.69) were positively correlated with the prevalence of overweight/obesity in primary students. Long screen time was also correlated to overweight/obesity primary boy students(OR=1.18). Family behavior factors for child overweight and obesity induded overweight of parents(OR-boy=1.29, OR-girl=1.23) and eating sweets(OR-boy=1.44, OR-girl=1.51). Irregular breakfast(OR=1.51), eating fast food(OR=1.22), drinking sweetened beverage (OR=1.75) and long visual screen time (OR=1.15) were also positively correlated with the prevalence of overweight/obesity in junior boy students. Conclusion Family behavior factors were positively correlated with the prevalence of overweight/obesity in primary and junior students. The influence of family behavior factors were different between primary and junior students. Behavioral interventions based on family should be adopted to prevent and control the overweight/obesity of children.

It is unknown whether the famous sex-related difference in emotion processing is accounted for by biological sex, gender role, or their interaction. To clarify the issue, in Study 1 we recorded event-related potentials in response to negative and positive images of diverse intensities when 47 masculine (26 males) and 47 feminine (22 males) subjects performed a non-emotional task. The occipital P1 and N1 amplitudes were larger in women than in men, while feminine subjects showed larger N1 amplitudes than masculine subjects, regardless of sex. Moreover, feminine subjects showed enhanced frontocentral N2 (210–270 ms) amplitudes for highly and mildly negative than for neutral stimuli, while masculine subjects showed an emotion effect only for highly negative stimuli. The feminine-specific effect for mildly negative stimuli was positively correlated to the feminine score, and this correlation was located to the anterior cingulate and the superior and medial frontal gyri. Furthermore, feminine but not masculine subjects showed enhanced parietal P3 (330–560 ms) amplitudes for highly and mildly positive than for neutral stimuli, an effect positively related to the feminine score and localized to the precuneus, posterior cingulate, and superior temporal gyrus. Machine learning analyses verified that single-trial N2 and P3 amplitudes of feminine subjects reliably discriminated the intensity of negative and positive stimuli, respectively. For ecological considerations, in Study 2 we used an observational approach (n = 300) and confirmed that feminine gender role, rather than biological sex, predicted individual differences in daily experience of emotion-related psychopathological symptoms. These findings provide solid evidence for the critical impact of gender role rather than sex on emotional susceptibility.

Facial and vocal expressions are essential modalities mediating the perception of emotion and social communication. Nonetheless, currently little is known about how emotion perception and its neural substrates differ across facial expression and vocal prosody. To clarify this issue, functional MRI scans were acquired in Study 1, in which participants were asked to discriminate the valence of emotional expression (angry, happy or neutral) from facial, vocal, or bimodal stimuli. In Study 2, we used an affective priming task (unimodal materials as primers and bimodal materials as target) and participants were asked to rate the intensity, valence, and arousal of the targets. Study 1 showed higher accuracy and shorter response latencies in the facial than in the vocal modality for a happy expression. Whole-brain analysis showed enhanced activation during facial compared to vocal emotions in the inferior temporal-occipital regions. Region of interest analysis showed a higher percentage signal change for facial than for vocal anger in the superior temporal sulcus. Study 2 showed that facial relative to vocal priming of anger had a greater influence on perceived emotion for bimodal targets, irrespective of the target valence. These findings suggest that facial expression is associated with enhanced emotion perception compared to equivalent vocal prosodies.
